Magic Packet technique is developed to remotely awake a computer host in a sleeping mode on a node through computer network. Instead of utilizing a large amount of memory or a complex algorithm, an algorithm and system, which only utilize two sets of counters and control logics to perfectly detect the Magic Packet according to the characteristics of magic packet are disclosed. According to the present invention, if a LAN controller on a node of the network is in magic packet mode, it will detect all input frames addressed in the node to search a specific data sequence indicative of the Magic Packet frame. Once the controller detects the data sequence, it will notice the power management circuitry of the computer host on the sleeping node to awake the system.
